Bussing in a major flight is idiotic. Cabin was too warm. Food was bland and felt old

Bussing in a major flight is idiotic. Cabin was too warm. Food was bland and felt old

Crew attendants attention to the travelers. Good food. I always fly with Turkish Airlines

Tv didn’t work and left the gate late but everything else was perfect.

Again poor use of old aircraft and old business class seats that show there age.

Service and food were very good, I liked it a lot. I liked the little gifts we all got , but I don’t think I’d fly on Turkish airlines to go to New York from Istanbul or from New York to Instanbul anymore. Flight is way too long.

We liked the comfort and seats. The crew was not very friendly nor did they check on us to see if we needed anything. Had to ask for water several times

The rules regarding business class lounge hotel/room access were very confusing. Between flights we had an 11 hour layover in Istanbul, but were denied a room to rest as our layover was too long?? Keep in mind that we arrived there at 3:30am after a long flight. Even multiple Turkish airlines employees were inconsistent with the rules. We ended up paying a high price at the Yotel in the airport in order to get some rest. Good thing I did, as a medical emergency was declared on the flight from Istanbul to Atlanta and I was apparently the only physician on board. Luckily I was able to stabilize the passenger and the flight wasn't diverted. The crew called an overhead announcement for a medical doctor, but insisted that I show them a copy of my medical license which I did. Very strange in my 35 years as a physician and responding multiple times to inflight medical emergencies over the years. I was very glad the passengers issue was resolved, but an acknowledgement of at least a thank you from the crew would have been appreciated.

The crew was awesome. My husband fell while traveling to the WC and got a head abrasion. The crew helped him greatly and a physician that was also on the flight checked him out as well. They all get an A+!

Same as before boarding process and lack of crew experience in the process

Excellent service. Made United 's business class look like a cattle car

Everything about the flight was excellent except for the fact that we had to wait one hour on the tar app and then I had to race to catch my connecting flight with the next stop

Way too crampled. Charge more and put in less seats.

This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

I liked the flight, the attendants, and the comfort. But the gate for boarding was poor. Even the elderly had to climb down many many steps to the bus and climb up to the plane.

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

Food is delicious I’ve tried Thai green chicken curry and it was perfect!

Flight was very late, meaning a missed connection in Frankfurt, and staff completely unhelpful or just absent. Handicap accommodations, reserved in advance, somehow never made it through the system for the second trip in a row!

During the boarding process women with small children were not invited to board first and were clumped into general crowd boarding, also during the 3 hr flight there was no food or water offered and I was traveling with a small child who needed water. I would appreciated that next time Luftansa informs that on 3 hr flight there would be no food or water offered so that I can prepare for the flight. In addition, traveling to the plane with the bus and then climbing up the stairs into the aircraft with small child and overhead luggage was probably the worst experience that I had in years traveling. Overall, will try to avoid traveling with Luftansa by all means. Thank you

Someones phone kept ringing and the flight assistant did nothing about it. Not even an announcement.

I had such a wonderful flight with Lufthansa. The crew was great and I was able to catch some much needed sleep. I look forward to using Lufthansa in the future!

I can't believe you have to pay L 3.20 for a Cup of British tea on an airlines with the name British on the plane.

Was very bad the cancel the flight after when we arrived to London

They lost my baggage and still waiting an update when I can receive it

American Airlines is the worst airline to fly. you can’t get on an earlier flight if you don’t have ‘status’, they cancel their flights with no warning, and they lie about why their flights are delayed so they don’t have to pay for meals or hotels. They lost me as a customer after this trip. I’ll be flying Delta or Untied from now on.

The checkin process is always horrendous with this airline. They never have enough people working the desk or people assisting in the lines. Rude and unbothered. I never pick British Airways- I always get swapped in via American Airlines and may need to stop using American Airlines as well. No entertainment in flight. And they seem more concerned about selling food and drinks then they are about customer comfort

Late from Istanbul. Canceled my seat to NY in London although I've been on time for boarding. Didn't provide with hotel and shuttle, no food, just sleeping and hygiene bag. Hope, they will refund me.

Terrible service. Stewardess behavior horrible. No sense of customer service. Seats were small, in general very bad experience which is not the case for me on other international flights via BA

Great!!! The first flight was a little painful because the chair wasn’t reclining and my back was destroyed by the time I got in London. But the second flight was perfect!! Super comfortable, the food was amazing, the crew super polite and helpful. Overall, I had a good experience

TIRED OLD plane. Seat cushion is completely old and NOT cushion at all; after an hour of flying butt hurts. Boarding is a complete disaster. No one respects the boarding groups, and the BA boarding crew care less about boarding groups or Tier status. What is the point of spending all this money on Business Class tickets when no one respects the boarding system? It took 90 minutes since we landed to get our luggage. 20 minutes to show on the screen which belt we are supposed to go to and another 1 hour to get our luggage - not the kind of service you will expect from BA at LHR

My ticket was cancelled unannounced and I was left stranded in the air port
